< cpp‎ | ranges‎ | lazy split view

struct value_type : ranges::view_interface<value_type> |  | (since C++20)

The value type of the iterator ranges::lazy_split_view<V, Pattern>::`outer_iterator`<Const>.

### Data members

Member | Description
`outer_iterator` `i_` (private) | an iterator into underlying `view` of the outer class (exposition-only member object*)

### Member functions

(constructor) | constructs a `value_type` object (exposition-only member function*)
begin | returns an `inner_iterator` to the beginning of the inner range (public member function)
end | returns a std::default_sentinel (public member function)
##### Inherited from std::ranges::view_interface
empty | returns whether the derived view is empty. Provided if it satisfies `sized_range` or `forward_range`. (public member function of `std::ranges::view_interface<D>`)
cbegin (C++23) | returns a constant iterator to the beginning of the range. (public member function of `std::ranges::view_interface<D>`)
cend (C++23) | returns a sentinel for the constant iterator of the range. (public member function of `std::ranges::view_interface<D>`)
operator bool | returns whether the derived view is not empty. Provided if ranges::empty is applicable to it. (public member function of `std::ranges::view_interface<D>`)
front | returns the first element in the derived view. Provided if it satisfies `forward_range`. (public member function of `std::ranges::view_interface<D>`)

### Member functions

## std::ranges::lazy_split_view::outer_iterator::value_type::value_type

constexpr explicit value_type(/*outer_iterator*/ i); // exposition only |  | (since C++20)

Initializes `i_` with std::move(i).

## std::ranges::lazy_split_view::outer_iterator::value_type::begin

constexpr /*inner_iterator*/<Const> begin() const; |  | (since C++20)

Equivalent to return /*inner_iterator*/<Const>{`i_`};.

## std::ranges::lazy_split_view::outer_iterator::value_type::end

constexpr std::default_sentinel_t end() const noexcept; |  | (since C++20)

Returns std::default_sentinel.

### Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR | Applied to | Behavior as published | Correct behavior
--- | --- | --- | ---
LWG 3593 | C++20 | `end` was not be noexcept | made noexcept
LWG 4013 | C++20 | `value_type` was default-initializable | not default-initializable
